So I just played Halo 2

Few questions.

  1. How did the Covenant find Installation 05 aka Delta Halo? I don’t think it is ever explained.

  2. When the In Amber Clad followed Regret from New Mombasa on October 20th and arrived at Delta Halo on November 2 that is almost a 2 week gap, however when the In Amber Clad jumps back into normal space you can see Miranda physically jolt forward and everyone acts as if it all was instant. What happened? Slipspace jumps are not instant, those 2 weeks would have actually been 2 weeks to everyone on board yet the game acts as if it all happened in the blink of an eye. You see the same thing in Halo 3 when the Covenant loyalists go through the portal to the Ark with the Separatists and Humans following, they were in Slipspace from November 17th to December 11th yet the game acts as i its still the same day.

  3. Near the end of the game John-117 aboard High Charity attempts to stop Truth from boarding the Forerunner Dreadnought and heading to Earth with his fleet. But John failed but stowed away onboard. What did this accomplish? Did Truth’s fleet follow him back to Earth or not? If so Cortana said that the UNSC forces would be crushed by that many Covenant ships yet they seemed to have been fine. And didn’t Truth already send his fleet to Earth? When Regret retreated on October 20h Truth had sent his Brute led forces to continue the attack on Earth, these are the forces that you fight in Halo 3 and ODST. So John attempting to stop Truth and boarding the Dreadnought accomplished what exactly?

  4. How did the UNSC forces get off Delta Halo and back to Earth? BEFORE John and Truth arrived on November 8th? Their ship the In Amber Clad was aboard High Charity controlled by The Flood. They didn’t have anyway to get off on their own, also how did they arrive at Earth, establish a base etc. before John did? The Dreadnought is a Forerunner ship which travels through Slipspace much faster than UNSC or Covenant ships.

  5. How did Truth know he needed the Dreadnought to activate the portal to the Ark on Earth? Where did he learn that? Also how did he know it was a portal?

  6. Halo 3 related question. How did High Charity get from Delta Halo to the Ark? The only real way is through the portal on Earth. So what the Flood controlled Covenant capital somehow went to Earth then through the portal ignoring the billions of hosts on the planet and go through to portal only arriving a little while after everyone else? How did High Charity even fit in that portal? High Charity was 216 miles long.

  1. They knew of all, if not, most of the Halos locations, its just they had to explore all of it in order to find the Index an the prophets also had to put on a show for the masses.

  2. Slip Space is a strange thing

  3. Truth didn’t care about the humans with the exception of MC and sent very few men to keep them in check. His fleet is the biggest due to him being the supreme overlord of the Covenant. John boarding the Dreadnought got him back to Earth in time to have a chance to stop Truth from winning.

  4. The Elites?

  5. He had studied the Forerunners and that led him to know of the “Hand”. He never knew of its whereabouts until he heard of Earth and thought it would be there because Humans are descendents of the Forerunners.

  6. ? You got me.

Thats not right.

  1. How? What evidence do we have they know the locations of the Halo rings?

  2. Thats not an answer.

  3. That really don’t answer my question ether.

  4. Still doesn’t explain how they got back before John and Truth.

  5. Thats not right ether. The Covenant knew locations of some Forerunner artifacts not because of large amounts of humans but because of their Luminary.

  6. Mhm

  1. I think it was just a blind jump that might have had external factors involved or something.

  2. I think that was just to make it seem instantaneous and cool, even if it wasn;t. There may also be a jolt for some slipspace jumps, too.

  3. Chief needed to get to Earth as soon as possible, and that seemed the quickest way for him. Plus it allowed Cortana to have a sort of mini-battle with Mendicant Bias.

  4. Chief crashes at night and is found during the day. Unless there was a sate during that cutscene that I forgot, then it’s possible that there’s an unspecified amount of time between Chief crashing and being found.

  5. I think Truth knew that there was a Forerunner artifact on Earth, and thought it was the Ark, but later discovered it was just the Portal. As for why he brought the Dreadnought, maybe he just assumed it would help? Again, him boarding the Dreadnought allowed Chief to board the Dreadnought, which allowed Cortana to deal with Mendicant Bias, which is a strong factor dealing with her lifespan.

  6. Not sure how big the Portal is, but I would think High Charity could still fit through it. The Gravemind on High Charity knew that the Covenant wanted to light the rings from The Ark. It was either “stay on Earth and infect Humans for a while” or “Get to The Ark, infect Humans and Covenant so they won’t fire the Halo Array, then come back to Earth and eat.” The Gravemind saw the second choice as the smarter one.

How did High Charity even fit in that portal? High Charity was 216 miles long.

  1. I believe there was a clue on Earth that lead Regret to Delta Halo. Just like the artifact on Sigma Octanus 4 stored the location of Installation 04, there was an object on Earth that held the location of Installation 05. It’s either that or Regret got very lucky.

  2. When in Slipspace, there are instruments that will let the ship know when they are about to exit Slipspace. So, anytime before hand, most of the crew will be put into cryo with a skeleton crew keeping the ship running. When they are about the enter normal space, the rest of the crew can be awoken at a moment’s notice. Since both In Amber Clad and the Separatist Fleets knew they would be fighting enemy forces on the otherside of their respective slipspace jumps, they likely brought the entire ship(s) to full combat alert in preperation for enemy engagement. It only seems like 1 day because we don’t see the time spent in Slipspace.

  3. If John couldn’t stop Truth, he needed to get back to Earth to help fight for the planet and Humanity. Now, the full force of the Covenant would have obliterated Earth’s forces. In Halo 3, Lord Hood is down to just a handful of ships for that major assault on the Dreadnought. However, Covenant Separatists were able to augment the remaining Human forces.

  4. The remaining UNSC forces hitched a ride back to Earth with the Arbiter and a few other Covie Separatist Forces. They were caught in a Slipspace wake that allowed them to arrive about the same time the Dreadnought did, November 8th. It would be another 9 days before Truth landed on Earth, giving Miranda and the Arbiter plenty of time to debrief Lord Hood and set up a base before the Chief would land on November 17.

  5. He found out somehow. Exactly how is unimportant. Remember, Truth knew about Earth, that it was the Human homeworld, and had amassed a huge fleet to attack. At some point, he discovered the location of the Portal and found out the Keyship would activate it.

  6. It’s likely that when the Gravemind got to Earth, it had learned about what the Ark could do, and made that a priority over infecting more people. As for how it fit: if a Halo can fit through the portal, I think High Charity can, too.

Hope this helps

  1. Mendicant bias had a personality fragment aboard high charity in the forerunner ship the city was built around. That’s how they knew the locations.

  2. Slipspace is a strange effect. While it may seem like an instant to the ones on board the ship it can be two weeks in real time, and vice versa. Slipspace time lapses work on the dyson theory. It’s way to complicated to explain, read glasslands.

  3. Truth never sent the entire covenant fleet anywhere. This eventually was his undoing. He was overly confident in his men and their capabilities and dramatically underestimated the humans.

  4. Just like the covenant the UNSC never sent their entire fighting force anywhere. Earth was the last line of defense. There was always a standing force protecting her.

  5. See point one.

  6. If a halo ring can fit through a slipspace portal then high charity can. But that’s beside the point. Once again mendicant bias had a fragment aboard high charity. Not to mention the flood as a race predate presumably everything in the universe. Their grave mind is innumerable in age and combines the absorbed knowledge of all the infected into its hive mind.

  1. They had set up High Charity right next to it, and on both Halos we’ve been on, the Covenant had completely dominated the Halo. There is no proof, so this is just a theory, but it is likely.

2.Was never meant to be an answer

  1. Once again, all speculation on a fan’s part, there is no real proof behind it because they never went that deep into it. Trust me, I still have a bunch of questions about what happened between Halo 2 and 3 because I think something bigger went on that we don’t know.

  2. Once again, no proof, there are a lot of things we don’t know because Bungie didn’t think that much of it. I’m just guessing the Elites.

  3. Once again for the third time, no proof.

  4. Mhm indeed.

A lot of things go unanswered because, and I’m going on personal opinion, its best that way. Mystery is what makes halo and all the unexplained events and actions leave you wanting more.

> 1. Mendicant bias had a personality fragment aboard high charity in the forerunner ship the city was built around. That’s how they knew the locations.

The fragment of Medicant Bias never helped the Covenant. It was dormant for a long time until the Covenant first encountered Humanity. After it tried to launch the Keyship, it was disconnected from the ship’s systems. It was dormant again until the Keyship docked on the Ark, and it merged wit the MB fragment there.

The Covenant never knew the locations of the Installations or the Ark until they were found the locations. They never knew the location of Installation 04 until Cortana made the jump toward it. They never knew the location of Installation 05 until Regret found it. The only exception may be the Portal on Earth, which it seems Truth discovered by some other means, but definitely not through MB.

  1. After arriving in system, truth stayed outside of earths orbit for some period of time before landing (I think it was a week?). I expect the ODST legendary ending has something to do with this.

Thanks. Two things though.

  1. Could G.S. have told them? They captured him on October 20th when they ransacked the gas mine on Threshold.

  2. Truth and John were both aboard the Dreadnought on their way to Earth, how would the Dreadnought arrive before John and Truth when they were on it?

1.In glasslands The unsc knows where several rings are and they only even knew they exsisted for like 6 years so the covies probably did to.

2.She probably did that because of the force created when exiting slipspace.

3.It got mc back to the fight which ended up winning them the war.

4.They hitched a ride with the elites.the arby/johnson/truth were on earth for a while b4 they found masterchief frozen in the forest.

5.The covies know alot about forunner artifacts it never says where he learned it.Probably the same place he learned how to activate the dreadnaught.

6.Gravemind=smart it knows what will happen if the ark is activated so it did what it could to stop it.the portal was Huge 3 high charities could have fit.

  1. We still don’t know as it is never brought up whatsoever along with how ONI found installation 03.

  2. I get you on this though the engine issue could have caused it.

  3. We have no clue since there isn’t a novel about halo 2 or 3 to explain these things so we have huge gaps in the plot. It wouldn’t be wrong to assume they got a ride from Rtas who jacked that brute carrier.

  4. Sigh Again bungie nor 343I seem to want to elaborate on the plot. Either High charity jumped directly to the Ark (Which it kind seems like in evolutions) Or it jumped directly into the portal on Earth. We just don’t know.

  1. I can’t remember where exactly, but I believe that I once read a ship reentering from slipsace doesn’t slow down as such but still goes through some form of deceleration.

Bump

For 1 and 5, Regret learned the location of both the Portal and Installation 05 during the Battle of Earth, hence his speedy exit. He learned this from data in The Superintendant from H3:ODST’s data center, since the humans had discovered it’s location shortly beforehand.

For #2, as others have explained, there is a time dilation effect in slipspace that is not always predictable. As for the jerk forward, In Amber Clad did not make an actual slipspace jump using their own drive core. They were dragged through slipspace through the slipspace rift made by regret’s ship.

As for #3, Noone seems to have mentioned the answer. Halo: Uprising, the first series of 4 Halo comics by Marvel tell of Chief’s time aboard the Forerunner Dreadnaught. His goal was to Assassinate Truth. At one point Hood tells him they are about to nuke it, and that he should get out of the blast area, which is when he drops from orbit down to Earth’s surface at the beginning of Halo 3. This same drop can also bee seen during Halo: Landfall, the live action series from Neill Blomkamp and Peter Jackson.
Also, The dreadnaught was a forerunner keyship, I.E. the thing required to unlock the portal. While Truth’s fleet had been on Earth digging up the artifact, it couldn’t do anything until Truth got there. Also, The dreadnaught was in our solar system for 9 days before it reached Earth.

For #4, as others mentioned, With the Arbiter and the Separatists.

As for #6, “As evidenced by Halo 3 and Halo 3: ODST, the Portal stretches from the edge of the metropolis of New Mombasa all the way to the edge of Voi. The distance between these cities is well over 100 kilometers. In this light, a diameter of mere 25.5 kilometers is an impossibility. This is further evidenced by the ending cutscene of Halo 3, where the Portal is seen from low orbit. It is clearly close to the African coastline instead of being deep into the mainland, which would inevitably be the case if the portal was only 25 kilometers in diameter.”

The Artifact is 100km wide, and High Charity is 348 km Wide so you make a -Yoink!- fine point.

For the rest of your question in #6, the Gravemind knew that the Ark was the means to fire the Halos (and to create new ones), so it ignored billions of hosts to try and prevent the halos from being fired again, which would have wiped out it and all of it’s potential future hosts.

Some other factors to keep in mind are things some people did or didn’t know. Truth knew Earth was humanity’s homeworld after the battle of Reach, but Regret did not, hence why he showed up so woefully unprepared. Truth had been amassing a fleet to attack Earth prior to this, but in between Halo 1, and 2, in the novel First Strike, Chief, Sgt. Johnson, and others succeed in an attack on it that prevents this full scale assault.

That was Truth not Regret and that was after Regret already fled to Delta Halo.

Also everyone seems to be saying the UNSC knew a bit about the Halo rings beforehand, where was this shown?

343 was only with the Rebels

What is the source for all that Toa? The dreadnaught didn’t go straight to Earth as in the uprising comic it was in orbit over mars.

Not true Thel 'Vadam killed Sesa 'Refumee and then Tartarus dropped in and took 343 G.S.

Sorry, let me clarify. There is clearly conjecture here, but I’ll try to back it up as best I can.

I meant that the UNSC may have had the data. This data likely had not yet been analyzed by a Smart AI or a human (like Dr. Halsey) who was sufficiently knowledgeable to be able to translate it. The SI had retrieved seismic data shortly before the battle of Earth, hence why Lt. Dare had already commissioned her team for the data retrieval. They were in mid-launch when Regret left. Regret did not know the Location of Installation 05 when he got to Earth, only that the portal to the Ark was on Earth and rushed there with a small force(which he did not know was the human homeworld, as Truth had not shared this data) so by that logic it must have been information he learned during the Battle of Earth/Invasion of Mombasa. It makes sense that upon it’s discovery, the excited Regret would go to investigate the “sacred ring” as quickly as possible. While it is POSSIBLE that he made a random jump, and just happened to arrive at Installation 05, I would suggest his jump was no more random than the jump Cortana made from Reach to Installation 04.

I am merely using interpolation using the data at my disposal to try to make sense of something that hasn’t been touched on in official canon.

In Halo 3, Lord Hood is down to just a handful of ships for that major assault on the Dreadnought. However, Covenant Separatists were able to augment the remaining Human forces.

They were caught in a Slipspace wake that allowed them to arrive about the same time the Dreadnought did, November 8th. It would be another 9 days before Truth landed on Earth, giving Miranda and the Arbiter plenty of time to debrief Lord Hood and set up a base before the Chief would land on November 17.

  1. It’s unlikely that G.S. was the one who told them the location, but still very possible. Again though, seems unlikely with Regret getting to the Installation first.

  2. The Dreadnought landed on Earth on November 17. When it entered the atmosphere, John broke off a piece and used it as a heat shield while re-entering.
